In September, Frank-Holm Rögner was invited to the Mid-Week Coffee Break of IVAM on behalf of the Fraunhofer FEP and as head of the Business Area Cleaning of Fraunhofer. In this networking event he reported on the topic "Cleaning of surfaces - knowing how to ensure best product properties". In a relaxed atmosphere, the members and participants were able to exchange ideas on the focus topic afterwards. The presentation is now available on YouTube.
